PHP Echo text Color

问题:

How do I change the color of an echo message and center the message in the PHP I've written. The line I have is:

echo 'Request has been sent. Please wait for my reply!';

回答1:

How about writing out some HTML tags and some CSS if you're outputting this to the browser?

echo '<span style="color:#AFA;text-align:center;">Request has been sent. Please wait for my reply!</span>';

Won't work from console though, only through browser.

How about writing out some escape sequences?

echo "\033[01;31m Request has been sent. Please wait for my reply! \033[0m";

Won't work through browser though, only from console ;))

And if you are using Command line on Windows, download a program ANSICON that enables console to accept color codes. ANSICON is available at https://github.com/adoxa/ansicon/releases

If you want send ANSI color to console, get this tiny package,

Try this

<?php 
echo '<i style="color:blue;font-size:30px;font-family:calibri ;">
      hello php color </i> ';
//we cannot use double quote after echo , it must be single quote.
?>

This is an old question, but no one responded to the question regarding centering text in a terminal.

/**
 * Centers a string of text in a terminal window
 *
 * @param string $text The text to center
 * @param string $pad_string If set, the string to pad with (eg. '=' for a nice header)
 *
 * @return string The padded result, ready to echo
 */
function center($text, $pad_string = ' ') {
    $window_size = (int) `tput cols`;
    return str_pad($text, $window_size, $pad_string, STR_PAD_BOTH)."\n";
}

echo center('foo');
echo center('bar baz', '=');

If it echoing out to a browser, you should use CSS. This would require also having the comment wrapped in an HTML tag. Something like:

echo '<p style="color: red; text-align: center">
      Request has been sent. Please wait for my reply!
      </p>';
